Site Survey
It is strongly recommended that a Site Survey is conducted prior to installation of a VDN Dualcom to confirm that adequate VDN signal strength
is available at the site.
Call a Help Desk. See page 10. Ask for a VDN signal strength prediction. For
this, you will need to have the Post Code of the site available. This will tell you
if there is VDN radio coverage at the proposed site.
If there is no VDN radio coverage at the proposed site, the Dualcom’s VDN
alarm reporting path will not operate. If your GSM mobile telephone operates at
the site you could consider using a CS2000 GSM Dualcom. Contact CSL for
more information.
You can use a Dualcom, aerial & fully charged battery to survey the proposed
site for the point of strongest signal. You can also use a portable CS1051 or
‘Pakit’ test set to show the VDN signal strength at the proposed site.
See Page 11 ‘Aerial Siting’ for more information. Make a note of this point and
use it when installing the Dualcom aerial.
